摘　　要：在密集取样分析并结合前人分析化验资料的基础上,建立苏北盆地高邮凹陷泰州组烃源岩地球化学剖面,对烃源岩进行综合评价,并用成因法对泰州组资源量进行预测。研究表明高邮凹陷泰州组二段中上部的暗色泥岩对油气成藏作用不大;泰州组二段底部的"六尖峰"段泥岩、泥灰岩有机碳平均为1.54%,干酪根为Ⅰ型和Ⅱ1型,处于低成熟—成熟阶段,为一套优质烃源岩;高邮凹陷剩余地质储量、可采储量分别为4254×104t、1293×104t,具有一定的勘探前景。The quality and potential of Taizhou Formation source rocks, Gaoyou sag, puzzled geologists. On the basis of closely spaced sampling analysis associated with former analysis data, the organic geochemical profile of Taizhou Formation was established. Source rocks were comprehensively evaluated, and the reserves of Taizhou Formation were predicted with genetic method. Shale at middle-upper section of Taizhou Formation is not much contributory for reservoirs, while shale and muddy limestone of six-sharp peak interval at the bottom of Taizhou Formation, with high organic carbon content （average 1. 54%）, sapropel type kerogen and low maturity-maturity, is a set of excellent source rocks. The reserves of the Gaoyou sag is 4 254× 10^4 t, and the recoverable reserves is 1 293× 10^4 t, which indicate that the Gaoyou sag has a good exploration prospect.
